Hello, I want to buy license for xenforo and I was going through licensing details page:- http://xenforo.com/purchase/ Can anyone clear my below doubts:- 1. Installation Service:- 50 $ - What exactly will you guys give in this installation service?? If I know how to install mybb then can I install this as well?? I guess installation should be straight forward and I don't need this license. Please clear my doubt in case installation requires some extra skills?? What exactly this installation is?? 2. XenForo Resource Manager - $60* - Is this giving interface to users for downloading something?? same like below:- http://xenforo.com/community/resources/ or this is license for downloading all the add-ons in future from:- http://xenforo.com/community/resources/ What exactly it is?? If it is first then I guess I don't need it coz I'm not allowing my users to download any thing from my forum?? Please clear my doubt that resource manger is only required for giving interface to my users to download?? 3. XenForo Enhanced Search - $50* Obviously I would like to go for it but can I buy it later when my forum will get bigger in size?? Also tell me when does this enhanced search will be useful in forum means how many minimum posts?? I guess forum having posts below 1 lakh don't need this enhances search as simple search will also be fast enough??
